空又は吸引カップを使用した吸引分娩器である。TECHNICAL BACKGROUND In some cases of childbirth, completely natural childbirth is not possible and assistance from an attendant is required to deliver the child. Such assistance may be provided by tweezers and similar other instruments. However, these devices tend to be large and difficult to manipulate, and their use can cause injury or discomfort to the mother and child. Another alternative to forceps is a suction delivery device that uses a vacuum or suction cup that attaches to the child's head.

である。A conventional vacuum delivery device is disclosed in US Pat. No. 3,202,152. The patent specification relates to a vacuum operator, specifically a vacuum cup, which is attached to a child's head, and an elongated stem connected to the vacuum cup and used to operate the cup so as to be able to apply traction to the child's head. It is described. Although the patent describes an effective vacuum delivery device, the device is cumbersome to position on the child's head.

帰した時所望の剛性を保有するように設計されている。The provision of a flexible portion 14c adjacent cup 30 allows the overall diameter of the device to be inserted into the birth canal to be minimized. This device has the smallest diameter or cross-sectional area when folded, allowing it to be inserted higher in the birth canal than other delivery devices. While the stem 14 is flexible, it is designed such that its flexible portion 14c retains the desired stiffness when returned to its extended state.

Allow characteristics. Flexibility of the flexible part is achieved by reducing the wall thickness. For example, the thickness of stem 14 over substantially its entire length may be approximately twice the thickness of flexible portion 14c, approximately 0.06 inches (0.1524 cm) and 0.03 inches (0.076 cm), respectively.

１５２号明細書に詳述されている。The cup 30 may have a series of reinforcing ribs 42 on its inner peripheral surface extending at approximately equal intervals from the vicinity of the opening 40 toward the opening of the front end portion 14a of the stem. The cup 30 is also provided with a vacuum distribution member 12 to protect the child's scalp from the suction force of the opening in the rear end 14a of the stem and to distribute the vacuum over a wide area over the child's scalp. A vacuum distributor 12 is provided over the inlet. Distributor 12 is U.S. Patent No. 3202
It is detailed in the specification of No. 152.
